LinkedList and ArrayList are two different implementations of the List interface.

This article explains the differences between ArrayList and LinkedList and in which case we should prefer the one over the other. ArrayList and Linked list both share the same properties due to inheritance of the same interface — List. But what is the difference between ArrayList and LinkedList? On the other hand LinkedList is better for inserting and removing data. Following table shows the average algorithm complexity by executing different operations on LinkedLists and ArrayLists. ArrayList vs.

ArrayList and LinkedList both implements List interface and their methods and results are almost identical. However there are few differences between them.
